27 Watt Explosion Proof Jelly Jar LED Light | 3780 Lumens | Class 1 Div 2 | 5000K | 100-277V | Surface Mount | Pendant Mount | Wall Mount

Product Overview

We supply a 27 Watt Explosion Proof Jelly Jar LED Light designed for hazardous location lighting where flammable gases, vapors, or dusts are present. This fixture delivers 3780 lumens at 5000K and operates on 100-277V. It is suitable for Class I Division 2, Class II Division 1 and 2, and Class III environments. Typical installations include paint booths, chemical processing areas, and solvent storage rooms where compliance and safety are critical.

The compact jelly jar form factor allows for surface, wall, or pendant mounting using a 3/4 inch NPT hub. This fixture is a direct replacement for legacy 175W metal halide units in hazardous and corrosive environments. The design supports both new construction and retrofit projects where explosion proof certification is required.

Core Performance and Output

This fixture provides 3780 lumens at 27 watts, achieving an efficacy of 140 lumens per watt. The 120° beam angle delivers wide, uniform coverage for task and general area lighting in hazardous locations. Color temperature is 5000K with a CRI above 70, supporting accurate visual inspection and color rendering in industrial settings.

Electrical performance includes a power factor above 0.95 and total harmonic distortion below 10%. The output level is suitable for mounting heights up to 12 feet in most hazardous location applications. At lower mounting heights, output may be excessive for confined spaces. Uniformity can decrease if spacing exceeds typical jelly jar layout patterns.

Adjustability and Control Options

This fixture supports 1-10V dimming for integration with compatible hazardous location dimming controls. Dimming allows for energy management and adaptation to changing task requirements. No field-adjustable optics or beam shaping accessories are available for this model.

Mounting orientation can be adjusted during installation, with surface, wall, and pendant options. The fixture is not designed for tilt or aiming adjustments after installation. Control wiring must comply with hazardous location requirements.

Longevity and Reliability

The LED array is rated for 50,000 hours (L70) at ambient temperatures typical of hazardous industrial environments. The copper-free aluminum housing and impact-resistant lens provide long-term durability against vibration, dust, and chemical exposure.

Ingress protection is IP66, and the fixture is rated IK10 for impact resistance. The design minimizes maintenance intervals and supports reliable operation in areas where access is limited or hazardous.

Build Quality and Physical Characteristics

The fixture housing is constructed from copper-free aluminum to prevent corrosion in chemical and marine environments. The lens is impact-resistant and sealed to prevent ingress of water and dust. The overall dimensions are 9 x 13 inches, with a total weight of 14 lbs.

All hardware and gasketing are specified for hazardous location use. The fixture is suitable for wet locations and marine outside type environments. Mounting options include surface, wall, and 3/4 inch NPT pendant configurations.

Where This Product Fits Best

This fixture is designed for hazardous and classified environments where explosion proof certification is required. It is commonly installed in areas with flammable gases, vapors, dusts, or fibers, including chemical processing, paint booths, and solvent storage. The compact form factor supports use in confined or low-ceiling spaces.

• hazardous location lighting
• explosion proof lighting
• paint booth lighting
• chemical processing facility lighting
• oil and gas facility lighting
• refinery lighting
• marine environment lighting
• solvent storage area lighting

The fixture is suitable for both indoor and outdoor hazardous locations, including marine and offshore environments. It withstands exposure to water, dust, and corrosive chemicals. Not intended for general-purpose industrial or warehouse lighting outside of classified areas.

Installation and Long-Term Use

Installation supports surface, wall, or pendant mounting using a 3/4 inch NPT hub. All wiring and mounting must comply with hazardous location codes and standards. The fixture?s weight and size allow for single-person installation in most cases.

Routine maintenance is minimized due to the sealed design and long LED life. Lens cleaning and periodic inspection of gaskets are recommended in environments with heavy dust or chemical exposure. Replacement is straightforward using standard hazardous location wiring practices.

How This Fixture Is Commonly Used

This fixture is typically mounted at heights from 8 to 12 feet in hazardous location corridors, process areas, and storage rooms. Spacing is determined by required light levels and the 120° beam spread, with typical layouts ranging from 10 to 15 feet apart for uniform coverage.

In paint booths and chemical storage, fixtures are often installed in continuous rows or perimeter patterns. Higher output reduces fixture count but may increase glare in small or reflective spaces. Layout should consider both code requirements and visual comfort.

Safety, Certifications, and Warranty

This fixture is certified to UL 844 for hazardous locations, including Class I Division 2 Groups A, B, C, D; Class II Division 1 Groups E, F, G; Class II Division 2 Groups F, G; and Class III. Additional certifications include UL 1598, UL 1598A Marine Outside Type, and ABS. The fixture is IP66 and IK10 rated.

Warranty coverage is 5 years. All certifications and ratings are maintained when installed according to manufacturer instructions and applicable codes.
